ventricles of the brain

ventricles of the brain

the cavities within the brain that are filled with cerebrospinal fluid, including the two lateral, the third, and (linked by the aqueduct) the fourth ventricles. They are lined by ependyma which, in certain regions, is invaginated by vascular fringes of pia mater to form the choroid plexuses.
